Click through the this link to Sierra Trading Post to grab today's barn burner deal. The SteriPen Traveler Mini Water Purifier for only $25. I've never used a SteriPen product before but I have heard a lot of very positive reviews about them. Seems like some pretty cheap insurance for water treatment.

Don't have any experience with this particular model, but I've been pretty happy with mine. Hasn't given me any trouble yet, but I've had trouble trusting it, and have traveled mostly with other folks who also had filters.

Still Herebeen scared and battered. My hopes the wind done scattered. Snow has friz me, Sun has baked me,Looks like between 'em they done Tried to make meStop laughin', stop lovin', stop livin'-- But I don't care! I'm still here! Langston Hughes

I've been looking to get one of these for a while, thanks for the heads-up!

I'll mirror the positive comments re: Steripens. The one problem I have noticed however is that they seem to not be a fan of the cold and/or altitude. We took two with us on Aconcagua and ended up having to drink iodine water above basecamp.

The mountains - whose summits reach or exceed arbitrary thresholds for elevation and prominence - are calling and I must go.

I got 4 rechargeable AA batteries in mine. They lasted for filtering liters and liters of water on Rainier for 4 people near 10k (my Steripen is a full version). Love the product - switched from Katadyn's water filter - big weight savings, and it is a very efficient/fast way to treat water. Coincidentally, GPS batteries are also AA, so there is a backup.
